Abstract: This is the first time it was shown that the nanoparticles of gold (Au) in substantial amount bind to the living biomass of the aquatic macrophyte, Ceratophyllum demersum. The concentrations of Au were measured in the samples of the phytomass using neutron activation analysis (NAA). As a result of the binding and/or immobilization of the nanoparticles, the amount of Au in the samples of the phytomass increased manifold (by a factor of 430) above the background level of gold in the plant tissues. The increase was by two orders of magnitude. The new data added some new information to the modern vision of the multifunctional role of the biota in the migration of elements in aquatic ecosystems. Also, the result added new information to the studies of interactions of Au with organisms that may contribute to new biotechnologies.

Abstract: Ostroumov S. A. Aquatic ecosystem as a bioreactor: water purification and some other functions. - Rivista di Biologia / Biology Forum. 2004. vol. 97. p. 39-50. The author formulated a new fundamental concept of aquatic ecosystem as a bioreactor that carries out the function of water purification in natural water bodies and streams. According to his new concept, the ecosystem as a bioreactor has the following characteristic attributes: (1) it is a large-scale (large-volume) bioreactor; (2) it is a diversified (in terms of the number of taxa and the scope of functional activities) bioreactor; (3) it possesses a broad range of biocatalytic (chemical-transforming and degrading) capabilities. New experimental data on xenobiotics-induced inhibition of the functioning of the molluscs Unio tumidus, U. pictorum, M. galloprovincialis and Limnaea stagnalisemphasize the potential ecological hazard from sublethal concentrations of pollutants (including those exemplified by synthetic surfactants and detergents).

ABSTRACT: Ostroumov S.A. On the biotic self-purification of aquatic ecosystems: elements of the theory. - Doklady Biological Sciences, V. 396, 2004, p. 206–211. (Translated from DAN, V.396, No.1, 2004, p.136–141). Fundamental elements are formulated for a new qualitative theory of the polyfunctional role of the biota in improving water quality and doing self-purification of water in aquatic ecosystems. The elements of the theory covers the following: sources of energy for the mechanisms of water self-purification; the main functional blocks of the system of self-purification; the system of the main processes that are involved; the analysis of the degree of participation of the main large taxa; the reliability of the mechanisms of water self-purification; regulation of the processes; the response of the mechanisms of water self-purification towards the external influences (man-made impacts, pollution); and some conclusions relevant to the practice of environment protection. In support of the theory, the results are given of the author's experiments which demonstrated the ability of some pollutants (surfactants, detergents, and some others) to inhibit the water filtration activity of marine filter-feeders, namely, the bivalve mollusks Mytilus galloprovincialis, Mytilus edulis, and Crassostrea gigas.

Ostroumov S. A., Walz N., Rusche R. Effect of a cationic amphiphilic compound on rotifers. - Doklady Biological Sciences. 2003. Vol. 390. p.252-255, Full text online free: http://www.scribd.com/doc/52634169/; https://www.researchgate.net/file.FileLoader.html?key=74bb403b372f3adc298aacbef568b0ee; [ISSN 0012-4966 (Print) 1608-3105 (Online)]. Welfare of the biosphere depends on filter-feeders that contribute to making water clean and transparent. Important new facts on the hazard of man-made damage to the beneficial function of rotifers, which are the plankton filter-feeders, were discovered. In this paper, it is the first time that it was found that a chemical pollutant inhibits filtration activity of rotifers. As a chemical pollutant, a representative of synthetic surfactants was studied. The study featured an advanced technique that allows precise measurement of the filtration rate on the basis of measuring the rate of removal of algal cells from water by rotifers. The experiment was run in the following system: the two-species culture of rotifers (Brachionus calyciflorus) and algae (Nannochloropsis limnetica; Eustigmatophyceae) was studied in a two-stage turbidostat (temperature 20 °C) as described by Walz et al. (1997) with some modifications. Dilution rate (the higher the filtration activity of rotifers, the higher the dilution rate) was monitored in the turbidostat. As a model of a chemical pollutant, the cationic surfactant tetradecyltrimethylammonium bromide (TDTMA) was added to the water of the turbidostat. On the basis of previous studies (Ostroumov, 2000), the concentration of TDTMA was 0.5 mg/L. Dynamics of the dilution rate before and after addition of the chemical was monitored. The dilution rate decreased after the addition of TDTMA. Also, a comparison of the dilution rate in the experimental turbidostat (with the surfactant) with the control turbidostat (without the chemical) was made. Under conditions of the addition of TDTMA the dilution rate was lower than in the control turbidostat. The lower dilution rate means a lower filtration and grazing activity of the population of the rotifers. The results are in accord with the hypothesis that the cationic surfactant TDTMA can inhibit the filtering activity of populations of rotifers. The results support the conclusions of previous publications, in which analogous effects of surfactants on another major group of filter-feeders (the bottom-dwelling bivalve mollusks) were discovered (Doklady of the Russian Academy of Sciences, 2001, 380, pp. 847-849; 2002, vol. 382, pp.138-141). www.springerlink.com/index/R3126462K122M13T.pdf; DOI 10.1023/A:1024417903077; Key words: effects, cationic amphiphilic substance, rotifers, two-species culture, rotifers Brachionus calyciflorus, algae Nannochloropsis limnetica, turbidostat, filtration activity, cationic surfactant tetradecyltrimethylammonium bromide TDTMA, grazing activity, filtering activity of populations, filter-feeders, chemical pollution, effects of pollutants, sublethal concentration, trophic interactions, man-made effects, anthropogenic,

ABSTRACT: The author obtained new data on coupling of geochemical and ecological (hydrobiological) processes. The role of freshwater mollusks Lymnaea stagnalis in the flows of chemical elements in the biosphere was studied by detecting the elemental composition and amount of pellets produced by the mollusks. For the first time, the following was quantitatively studied: the elemental composition (C, N, P, Si, Al) of pellets formed by mollusks Lymnaea stagnalis feeding on the leaves of higher plants Nuphar lutea and Taraxacum officinale; the amount (wet weight, dry weight) of pellets formed by L. stagnalis feeding on the leaves of N. lutea and T. officinale; the transfer of matter and chemical elements (C, N, P, Si, Al) with pellets of freshwater bivalves (unionids freshwater mussels Unio sp., etc.) per unit biomass of mollusks and per unit area of the ecosystem of the river; the transfer of matter and chemical elements (C, N, P, Si, Al) with pellets of L. stagnalis per unit biomass of mollusks and per unit area of the ecosystem of the pond. Synthetic surfactants ТDТМА 2 mg/l, SDS 1-2 mg/l, detergent Tide-Lemon 75 mg/l inhibited the trophic activity of L. stagnalis. Percents of food assimilability of taxons of invertebrates, from Rotatoria (48-80) to Diptera (1-31)].

ABSTRACT: Effects of amphiphilic chemicals on filter-feeding marine organisms. (author: S.A.Ostroumov, Moscow State University).
For the first time, oysters were used as the test-organisms in bioassay of synthetic surfactants. As surfactants are one of key components of water pollution from municipal waste waters, from ports and ships, the new data revealed a novel type of hazard to mariculture of oysters. New negative effects of several amphiphilic chemicals (surfactants) and chemical mixtures on oysters and other marine bivalves were discovered. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA) inhibited water filtering activity of oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixture products (detergents) that included surfactants as components of the mixtures. Those mixture products inhibited filtering activity by Crassostrea gigas and Mytilus galloprovincialis. The mixture products tested were: the SD1(L), Lanza-automat (Benckiser); SD2(I), IXI Bio-Plus (Cussons); LD1 (E), dish washing liquid E (Cussons International, Ltd.); and LD2 (F), dish washing liquid Fairy (Procter & Gamble, Ltd.). The new results are in agreement with the author’s previous experiments, where a number of xenobiotics and/or pollutants inhibited the filtering activity of several species of marine and freshwater bivalves. The filtering activity contributes to improving water quality. This experimental approach is helpful in assessment of environmental hazard from man-made chemicals that contaminate marine ecosystems.

The author discovered and characterized a new type of ecological hazard of chemical pollution of water, which involves inhibition of important processes of ecological remediation of ecosystems (water filtration by aquatic bivalves). Experiments were performed using mollusks (oysters), Crassostrea gigas Thunberg, and a cell suspension of Saccharomyces cerevisiae. The cell suspension was a model of suspended matter in aquatic ecosystem; this species of one-cell organisms was taken just for convenience, as a model of suspended particles. Laundry detergent Lanza-Automat inhibited water filtration by oysters (Crassostrea gigas). As a result, the removal of the suspended particles (cells Saccharomyces cerevisiae) from water was inhibited. This demonstrated a new type of ecological hazard caused by water pollution with chemical pollutants at sublethal concentrations. This hazard is associated with the fact that chemical pollution of water causes inhibition of the physiological activity of filter-feeders, thereby inhibiting the important ecological processes of water filtration. These ecological processes contribute significantly to improving water quality, water purification and the related remediation of aquatic ecosystems (their ecological repair). ---http://scipeople.ru/users/2943391/; [http://www.springer.com/life+sci/journal/10630] also see: http://sites.google.com/site/bioeffectsofsurfactants/ http://sites.google.com/site/surfactantinhibitfilterfeed02/ http://sites.google.com/site/3surfactantsfiltrationmytilus/ http://sites.google.com/site/ostroumovsergei/ http://sites.google.com/site/bioticupgradewaterquality2008/ --Key words: discovery, new ecological hazard, chemical pollution, water, inhibition, ecological remediation, ecosystems, water filtration, aquatic, marine, bivalves, mollusks, oysters, Crassostrea gigas Thunberg, Saccharomyces cerevisiae, suspended matter, laundry detergent Lanza-Automat, removal of the cells, pollutants, sublethal concentrations, filter-feeders, improving water quality, self-purification, remediation, ecological repair; mariculture, the Black Sea, Mytilus edulis, Dreissena polymorpha, Unio tumidus, M. galloprovincialis, Ephemeroptera, Brachionus calyciflorus, Cladocera, Potassium bichromate, Triton X-100, detergent OMO, Pesticides, cationic surfactant TDTMA, fungicide Carbendazim, kaolin particles, Isochrystis galbana, tetradecylcetyltrimethylammonium bromide, SDS, sodium dodecylsulfate, detergent IXI Bio-Plus (Cussons), dish washing liquid E, dish washing liquid Fairy, shampoo Avon Hair Care, bioassay, biotest, ecotoxicology, benthos.

System of principles for conservation of the biogeocenotic function and the biodiversity of filter-feeders.- Doklady Biological Sciences. 2002 (March). Vol. 383: 147-150. Bibliogr.15 refs. ISSN 0012-4966 (Print) 1608-3105 (Online). Distributed by Springer, orderdept@springer-sbm.com.
ABSTRACT: As a result of the author’s studies of filter-feeders (DAN, 1998, Vol. 362, P. 574-576; DAN, 2001, Vol. 378, P. 283-285), it is clear that the filtering activity of populations of filter-feeders in natural habitats might be significantly reduced if the concentrations of some pollutants reach certain levels. The role of filter-feeders as factors of water purification in ecosystems is so important that their inhibition is a danger for the entire ecosystem. The author emphasizes that not only the biodiversity of filter-feeders but also their level of functional (filtration) activity is to be protected. In order to do so, the author suggested establishing a new type of protected areas whose main purpose is to protect functionally active populations of filter-feeders, including bivalves and other organisms. Those protected areas could be named hydrobiological (some variants: biofiltering, or malacological) reserves (some variants: refuges, sanctuaries, etc.). The author formulated 5 principles of nature conservation requirements in malacological and hydrobiological reserves (Tabl. 3). Among them is principle 2, "conservation of filtration activity of organisms and populations". The paper contains data on how 5 detergents (1-50 mg/L) inhibited the filtration activity of Unio tumidus, Mytilus galloprovincialis, Crassostrea gigas (Tabl. 2); on effects on the efficiency of elimination (EEE) of suspended matter from water were measured (Tabl. 2); on the number of days (0.3 – 10) needed to filter the volume of aquatic (freshwater and marine) ecosystem by the local bivalves (a review of data from literature) (Tabl. 1). "I suggest that the existing system of protected terrestrial and water areas should be supplemented with special sites intended to conserve populations of filter-feeders. In addition to biodiversity conservation, these populations should be conserved because they fulfill a very important biogeocenotic function of water filtration and purification" (p.149). "The system of five principles…is proposed to provide an ecological basis of the environment conservation conditions at these sites (malacological and hydrobiological reserves)" (p.149).].

Vol. 383 (1-6): 127-130. Bibliogr.15. ISSN 0012-4966. Abstract. The paper presents a discovery of a new type of negative impact of pollutants on the biosphere, as a result of inhibition of water filtration by filter-feeders / suspension feeders. The water filtration and associated removal of suspended matter from water is part of migration of matter. As V.I. Vernadsky stressed, organisms are mediators of “biogenic migration of atoms in the biosphere”. This migration is partly implemented in the framework of pelagial–benthal coupling via the activity of filter-feeders, which remove the organic suspended matter from water and excrete pellets. The tables contains the following data: the average percentage of assimilated (16-90%) and non-assimilated (10-84%) food matter for 15 large taxa of invertebrates (Table 1); potassium bichromate inhibited water filtration by mussels Mytilus galloprovincialis (Table 2); surfactants, detergents, pesticides inhibited filtration by filter-feeders, marine and freshwater bivalves and rotifers (Table 3). A prediction was made: "Further research and experimental studies are expected to provide new evidence that sublethal concentrations of chemical pollutants induce a significant decrease in the filtration capacity of freshwater and marine filter feeders" (p.129). "The uncoupling process considered above is an anthropogenic violation of two basic laws (empirical rules or biogeochemical principles) of the biosphere functioning: (1) biogenic migration of atoms of chemical elements in the biosphere always tends toward its maximum expression; (2) on the geological time scale, the evolution of species gives rise to the forms of life that are stable in the biosphere, and is so directed that the biogenic migration of atoms in the biosphere increases" (p.129).]; DOI10.1023/A:1015385723150; https://www.researchgate.net/file.FileLoader.html?key=d988acb599e121964c48114374a87e8d;www.springerlink.com/index/28V23JBFADL1Y100.pdf;

It is the first paper that reported two new experimental results. First, the new author’s experiments measured the biota-driven fluxes of the matter and chemical elements in a model ecosystem. Second, the authors got another innovative result: a discovery of effects of chemical pollutants. Namely, these biota-driven flows of the chemical elements were decreased by a chemical pollutant exemplified by a synthetic surfactant.

It is the first paper in which it was clearly shown that aquatic biota (the sum of organisms) is the core part of the ecological mechanism of water self-purification in healthy aquatic ecosystems. The important attributes of this core part of the mechanism are: 1) lability; 2) vulnerability to anthropogenic impact.
Self-purification of water is a complex process including physical, chemical, and biological components [1–3]. The vulnerability of different components of the water self-purification system to anthropogenic factors is as yet insufficiently understood. The goal of this work was to review the literature and our own unpublished experimental findings concerning potential vulnerability of the biotic component of the water self-purification system to chemical pollutants.

------------Abstract. The author gave innovative analysis of the vital role of filter-feeders in functioning and maintenance of stability of aquatic ecosystems (both freshwater and marine ecosystems). The paper includes the following tables. Table 1. Examples of the impact of filter-feeders on the water column: clearance time. Table 2. Examples of diversity of taxa of benthic organisms involved in removing seston from water, and filtration rates. Table 3. Effect of the increase in concentration of algae on the filtration rate and the amount consumed by rotifers Brachionus calyciflorus. Table 4. The ratio F:P in some groups of organisms (examples of "ecological taxation"). Table 5. The ratio F: (P+R) in some filter feeders. Table 6. Results of the ecological tax: biosediment formation in 6 ecosystems. Table 7. Contribution of various aquatic organisms to oxidation of organic matter in the ecosystem of the Sea of Okhotsk. Table 8. Some chemicals that inhibit the filtering activity of the filter-feeders (new data of the author). Table 9. Some features of water-filtering biomachinery: 6 fundamental principles. Table 10. The level-block approach to the analysis of ecological hazards of anthropogenic effects on the biota (the new conceptualization proposed by the author). Some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality, (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3) the role of contributing to creation of habitat heterogeneity, (4) the role of contributing to acceleration of migration of chemical elements. It is an important feature of the biomachinery of filter-feeders that it removes from water various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole. The new experiments by the author additionally demonstrated a vulnerability of the filtration activity of filter feeders (e.g. bivalves and rotifers) to some xenobiotics (tetradecyltrymethylammonium bromide, heavy metals and some others). The inhibition of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological … of the second type.

(Translated from Doklady Akademii Nauk, 2000, Vol. 375, No. 6, p. 847–849). Abstract: In the paper, the author proposed a new approach to analyze the key ecological issue, the interactions between organisms in ecosystems. The new methodology proposed is inhibitory analysis. The author applied this approach to analyze trophic chains: the top–down control of plankton by benthic filter-feeders. This control, as the author’s experiments have shown, might be removed by chemical inhibitors (the latter may enter the ecosystem as pollutants). As an example, the author gives the results of his experiments on how surfactants [tetradecyltrimethylammonium bromide (TDTMA)] and synthetic detergents inhibited the control of plankton (Monochrystis lutheri) by mussels Mytilus galloprovincialis. The method was successfully applied to innovatively analyze the factors that are among reasons of eutrophication. Among new facts: the cationic surfactant TDTMA 1 mg/L inhibited the filtration rate of juveniles of marine bivalves Mytilus galloprovincialis, and the removal of cells of the algae Monochrysis lutheri from water (50 min, 26˚C)].

Abstract: The study of water self-purification processes (Skurlatov, 1988; Ostroumov, 2000a) is essential for approaching fundamental ecological problems (Alimov, 2000; Ostroumov et al., 2003) and for resolving some applied issues related to the sustainable use of aquatic and biological resources. The purpose of this paper is to give a systematic account of the concepts concerning the multiple functions of the biota in the self-purification of water bodies and watercourses, without attempting to review the numerous publications in this field. In this paper, a paradigm shift was made and some new principles of the theory of the ecological mechanism of water self-purification based on multiple functions of the biota in freshwater and marine ecosystems were formulated. In developing this theory, the results of the author’s experiments with aquatic organisms (filter-feeders) have been used. As a result, the author discovered that the natural ecological mechanism which maintains water quality (water self-purification mechanism) is vulnerable to the impact of some pollutants as exemplified by synthetic detergents and surfactants. Conclusions drawn on the basis of the theory have practical significance for biodiversity conservation and for the sustainable use of the biological resources of aquatic ecosystems. 1067-4136/05/3606-0414 © 2005 Pleiades Publishing, Inc.

Abstract: Macrophytes are important components of ecosystems and participate in the purification of water, which contributes to the sustainability of water quality. This is especially important in conditions of pollution of water bodies and water streams. Surfactants constitute an important class of pollutants. Therefore, further investigation and clarification of the facts concerning the interaction of plants and various surfactants are necessary. The present paper presents the results of investigations of the effect of various concentrations of aqueous solutions of the anionic surfactant sodium dodecyl sulphate (SDS) on the viability of the aquatic macrophytes, the pondweed Potamogeton crispus L. When the effects of the anionic surfactant sodium dodecyl sulphate on the aquatic macrophytes Potamogeton crispus L. were studied, it was found that the concentrations of 83–133 mg/l caused fragmentation of the stems of plants. The tolerance of the plants to the negative effects of the surfactant was higher in the spring (April) than in the autumn (September).
